Not exactly. 22 is the default port for ssh. ssh, as used in this
thread, can be thought of as encrypted telnet, though ssh can do much
more. ssh != vpn. Once you have a VPN established, you can use an ssh
application to open up a terminal session to a system at work, just like
you do when you are at work (assuming you use terminal sessions at work,
if not, sorry for the added confusion). VPNs will use some negotiated
port, e.g., 1582, as the secure communications channel between your home
system and your work VPN server, but it will never use one of the
well-known ports (like 22 for ssh or 21 for ftp).
